ORLANDO, Fla. — Early this month, the shutdown of the Disney Channel Rocks attraction at Disney World erased the last theme-park reference to the highly profitable High School Musical.

Ashley Tisdale — who found fame through the movies as singing, sniping “mean girl” Sharpay — isn’t shedding any tears.

“It’s been a few years, so we’ve moved on, and I guess the fans have, too,” said Tisdale, referring to the 2011 swan song, Sharpay’s Fabulous Adventure.

“But we had a great run.”

Tisdale, 27, a New Jersey native in “the business” since age 3, knows not to become sentimental about past work. She still does Disney projects; her Blondie Girl Production company just produced a Disney Channel movie, Cloud Nine.

Tisdale, though, left her “good girl” image behind when she posed nude for Allure magazine a few years ago. She even guest-starred last year on the cable drama Sons of Anarchy.

And now she’s taken on “the blonde” role in the Scary Movie franchise, in essence replacing Anna Faris, who appeared in several of the earlier films in the series. Tisdale was surprised by the lengths the producers went to in ensuring that the horror parody “was totally up to date.”

“They even got a reference or two to Evil Dead, just working off the trailer to that one,” she said.

Tisdale did a version of horror’s stunt du jour, which has turned up in films such as Paranormal Activity and Evil Dead. The stunt shows an actor or actress dragged suddenly out of the frame and into the darkness.

“They strap you in this harness, put your costume over it and yank you. It’s pretty simple. They don’t have to surprise you with it. Your reaction’s where the acting comes in. You’ve got to give them that terrified face as you’re pulled away from the camera. And you want to get it right the first time because it’s not fun, getting yanked like that.”

Tisdale grew a worldwide fan base, thanks to High School Musical and the record deal (two solo albums thus far) that came from it. But she is happy that the comically terrified mom she plays in Scary Movie V is a new role for her.

“This is a lot edgier than anything I’ve been in before,” she said, “and hopefully it’ll surprise people.”

She is set to co-star in a big-budget version of the Rapture series — Left Behind, with Nicolas Cage — that could start shooting in May. And after that?
